IMPROVEMENT lN BOTTLE-STOPPER FASTENERS.

Specification forming part of Letters Patent No. 206,525, dated July 30, 1878; application filed February 8, 1878.

To all whom it may concern:

Be it known that I, ALBRECHT E. BARTHEL, ofDetroit, in the county of \Vayne and State of Michigan, have invented an Improvement in Bottle-Stoppers, of which the following is a specification The nature of my invention relates to certain new and useful improvements in bottlestoppers, and devices for securing them to the bottle and in place; and the invention consists in the peculiar construction and arrangement of the various parts, as more fully hereinafter set forth.

Figure 1 is a perspective view of a section of abottle with my improved devices attached. Fig. 2 is a vertical section of the same. Fig. 3 is a side elevation. Fig. 4 is a perspective view of a plain rubber plate, adapted for use with my invention. Fig. 5 is a perspective view of the neck-wire, provided with removable yoke attachments.

In the drawing, A represents the neck of a bottle, provided with the head B, usually found in bottles for holding effervescing liquids. Around the neck of this bottle, below said head, is twisted the neck-wire R, to which are secured on opposite sides the boxes or bearings O, which may be stamped out and sleeved upon said wire, as at Fig. 5. These boxes should be perforated with two holes, as shown, said holes being in vertical relation to each other, to receive the inturning ends of the yoke 13, the vertical position of the holes allowing said yoke to be sprung into either pair of said holes, as the tension upon the stopper may require. This yoke is bent from one piece of wire, as shown in Figs. 2 and 4, and its top is bent downward, as shown in Figs. 1 and 2, to form a bearing for the bifurcated cam F, which is provided with a lever, G. Sleeved upon this yoke is the metallic plate or cap O, provided with perforated ears 0 for that purpose, and having a depressed center, 0. A flat rubber to rise under the pressure in the bottle, when the yoke may be thrown to one side, leaving the bottle open. The plate 0 is provided, as shown, with a downward projection, c, in order to press the plate D into the neck of the bottle.

Should the flat elastic plate D become so compressed by use that the leverage secured by the yoke engaging with the upper holes in the bearings does not perfectly close the mouth of the bottle, the cap 0 may be shoved upward upon the yoke sufficiently to allow the hook-journals to be disengaged from the upper bearing-holes, and engage with the lower pair of holes, when the leverage lost by such compression would at once be restored. By having the lever G of the shape shown, so that it projects down on the side of the head of the bottle and close to the same, and by having its cam-portion F of the broad form shown, and situated under the yoke when locked, it will more securely hold the stopper in position in the neck of the bottle, and with less danger of its being accidentally released, while it can be conveniently raised, when desired, by pressing upon its lower bent end, which hangs down about opposite the neckwire. The depressed center of the cap 0 presses the flat rubber plate tightly into the neck of the bottle, and both of these parts being imperforate, (except their ears 0 (7,) the bottle will be closed air-tight.

The bearing-boxes O, strung on the neck wire, form very simple, easily-applied, and efficient means for adjustably pivoting the lower ends of the yoke to the neck-wire.

By having the flat rubber plate D separate from the cap C, it can be easily replaced by a new plate when worn from being pressed and expanded into the neck of the bottle. This can be easily done by springing the ends of the yoke out of the boxes on the neckwire, and removing the rubber plate by slipping it downwardly on the yoke. A new plate can then be put on the yoke in place of the first one, and the ends of the yoke again sprung into the holes in the bearing-boxes. The per forated ears of the rubber plate retain it securely in position on the yoke without being connected with the cap.

W'hat I claim as my invention is wire B and the bearing-boxes C, strung upon 1. The combination of the yoke 13, pivoted such neck-wire and provided with Verticallyto the neck-Wire, the lever G, having cam F, arranged holes, forming an adjustable pivot pivoted upon the said yoke, the cap 0, with for the lower ends of the yoke, constructed depressed center 0, and the flat rubber plate substantially as described and shown. D below such cap, both said cap and plate being provided with perforated ears, through ALBRECHT BARTHEL' which the arms of the yoke pass, substantially WVitnesses: as described and shown. H. S.
